Recently, a confirmatory study data from a domestic research team showed that the pathogenicity of this strain in Omi clone showed a geometric decrease in the number of pathogenicity of the strain in Omi clone compared with the original strain and other subsequent strains of the new coronary pneumonia.
This shows that we no longer have to panic about the new coronavirus, and the harm of the new coronavirus to the human body is not as serious as in the past. Does this indicate that COVID-19 will gradually become a common flu in the future?
1. What does the reduction in the pathogenicity of the new coronavirus mean?
Domestic research found that the pathogenicity of Omickron mutant strain and original strain has decreased by about 30%. The results show that compared with the initial strain, the pathogenicity and virility of the Omickron variant strain have significantly decreased.
For the general population, under the protection of the vaccine , the harm of new coronary pneumonia is no longer as serious as before. However, we should not relax our vigilance against COVID-19. Experts also said that it is too early to call COVID-19 a common flu. First of all, the two are not the same type of disease. Secondly, although the mortality rate of the COVID-19 virus is on a downward trend, the evolution of the virus still takes a long process.
There is a possibility whether the new crown will become like the flu in the future, but it is not possible to make a rash judgment at present. Recently, the data on daily new infections across the country have continued to fluctuate and rise, and the epidemic continues to show the characteristics of many points, wide range and frequent occurrence. The situation is severe and complicated. Due to the concealment of Omikron's transmission, the overlap between cross-provincial transmission and the new and old epidemics is still very serious.
2. Will the current domestic epidemic prevention and control strategy change?
The 20 new epidemic prevention regulations recently issued not only optimize the details of precise prevention and control, but also provide new instructions on some deviations and omissions in prevention and control.
Recently, many cities across the country have issued documents announcing that people who have no social activities such as the elderly, home office and study personnel, infants and young children who have lived at home for a long time and who have no need to go out can not participate in community nucleic acid screening. This shows that the current epidemic prevention and control strategy is not static.
Recently, the National Health Commission also stated that it will adhere to the overall strategy of " dynamically clearing ". On the basis of summarizing the effectiveness of epidemic prevention and control practices and policy implementation in various places, epidemic prevention measures will be continuously optimized and improved based on changes in the latent time, transmission routes and pathogenic ability of the new coronavirus.
eliminates local silence management; strictly prohibits "level increase" and "one-size-fits-all" epidemic prevention measures; severely punish institutions that issue false nucleic acid results in accordance with the law; strengthen supervision of third-party nucleic acid testing institutions.
3. How should ordinary people deal with the new round of epidemic in winter?
Entering winter, the epidemic situation in many places has rebounded. At present, the epidemic prevention and control situation remains severe. Everyone should still maintain regular nucleic acid, be vigilant at all times, wash hands frequently, wear masks, maintain social distance and indoor ventilation.
Personal protection is one of the most effective measures to prevent and control the new coronavirus. At the same time, try not to travel unnecessary to reduce the possibility of contact with the virus.
